Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

Papapetrou line element describes an axial symmetric stationary spacetimes and the coordinates that appear in this metric are just similar to cylindrical coordinates; I mean they are labeled ρ, z and phi. I want to know if they are really the cylindrical coordinate or not; In other words, are their transformation to spherical or cartesian coordinates the same as what we have in the literature?

So thanks in advance,

Saeide
